Due to a combination of crew errors the autobrake was inadvertently disarmed without the crew being aware. From that experience, the operator mandated that autobrakes were to be armed for every landing on its 737 fleet, regardless that the incident aircraft was a Boeing 747.
I don't follow the logic here. The auto brakes were armed and then disarmed without the crew realising; so how does arming them as an SOP solve anything?
